Which of the following technologies can be used to describe RESTful Webservices? Choose one answer.
-
WSDL
-
ebXML
-
UDDI
-
None of the above.
WSDL is designed for SOAP services and doesn't naturally describe REST's resource-oriented architecture. ebXML is for electronic business XML exchanges, UDDI is a registry for service discovery, and none of these are standard REST description languages. While WADL (Web Application Description Language) exists for REST, it's not widely adopted, making 'None of the above' the correct answer.
WSDL, UDDI, and ebXML are all artifacts of the SOAP/XML web-services stack (service description, discovery registry, and business-to-business messaging respectively) and don't apply to describing RESTful services, which typically rely on plain documentation, OpenAPI/Swagger, or similar — none of which appear in the list. So "none of the above" is the correct choice among these SOAP-era options.
